Assignment

Junction capacity & signal optimisation

Compare junction layouts and signal strategies before committing to an intervention.

Aerial view of traffic and pedestrian crossings at a city junction

The challenge

A busy junction experiences queues, uneven delays and difficult pedestrian crossings. The authority needs to compare workable improvements.

The approach

  1. Collect turning counts, queue observations and pedestrian movements.
  2. Build and check a baseline model against observed operation.
  3. Compare layout, signal timing and crossing alternatives under agreed demand scenarios.

Decision supported

Choose an intervention using capacity, delay, accessibility and operational trade-offs.
